Our Window Range

If you are upgrading a traditional property or adding the finishing touches to a modern build, our expert fitters deliver high-quality craftsmanship backed by a comprehensive 10-year guarantee. Upgrading your windows can even increase your property’s value by up to 10%. We offer a diverse selection of window materials and window styles, with a huge range of options to help you find the right balance of aesthetics, performance, and budget.

uPVC Windows: durable, insulating, and low maintenance

Our A-rated double-glazed uPVC windows are a highly popular choice for Hamilton homeowners looking for everyday reliability, strong energy efficiency, and excellent value, with rated windows that help improve comfort year-round.

  • Energy Savings: Designed for outstanding thermal performance, these windows deliver exceptional energy efficiency through better insulation that helps keep each room warmer and can help you save money by reducing heat loss and lowering energy costs.
  • Noise Reduction: Modern uPVC double and triple glazing can lower external noise by 25 to 35 decibels, making your indoor space much quieter and more peaceful.
  • Longevity: With proper installation, high-quality uPVC windows typically last between 20 and 35 years. Multi-chambered uPVC frames improve durability and strength, support modern security features, and selected systems can meet PAS 24 Enhanced Security standards.
  • Versatile Styles: Available in a range of window styles, including flush sash options, practical turn windows that allow for controlled ventilation and easy cleaning, classic casement windows, and sash horn designs that replicate the detailing of traditional timber.
Virtually no maintenance · never needs painting or treating

Aluminium Windows: sleek, modern, and exceptionally strong

For a contemporary aesthetic and unparalleled durability, our premium aluminium windows are the ultimate architectural choice.

  • Slimline Frames: Because aluminium is incredibly strong yet lightweight, the frames can be manufactured much thinner, allowing for larger panes of glass and uninterrupted panoramic views.
  • Weather Resistance: Aluminium is naturally resistant to corrosion, moisture, and warping, making it perfectly suited to endure harsh wind-driven rain and damp weather.
  • Exceptional Lifespan: With durable powder-coated finishes, our aluminium windows can last between 30 and 45 years—and sometimes up to 60 years with simple, occasional maintenance.
  • Customisable: Choose from an extensive range of colours to perfectly match your home’s exterior and interior decor.
30–45 years · up to 60 with occasional maintenance

Composite Windows: the best of both worlds

For those who refuse to compromise, composite windows blend the natural beauty and superior insulation of timber on the inside with the resilient, weatherproof protection of aluminium on the outside, giving homeowners the look of traditional timber with modern weather protection.

  • Ultimate Thermal Performance: The timber core acts as a natural insulator, and with double glazing available, achieves outstanding energy ratings while keeping your home exceptionally warm during the Scottish winter.
  • Zero Exterior Maintenance: The external aluminium cladding protects the wood from the elements, meaning you get the classic look of timber without the hassle of sanding, varnishing, or repainting.
  • Luxury Aesthetic: Perfect for bringing a warm, traditional feel to your interior space while maintaining a sharp, modern, and highly durable exterior.

Doors: matching doors, fitted at the same time

If you’re comparing double glazing Hamilton solutions, we can also advise on matching doors where available — and the 40% applies to them too.

  • Insulation and security: Modern doors can support insulation and security, with multi-point locking systems as standard.
  • Quieter again: Noise reduction often improves further when older windows and doors are replaced together.
  • The full range: Composite Doors, Aluminium Bi-fold Doors, Patio Doors, French Doors and Specialist Doors.

Can’t fault this company any shape or form

Can’t fault this company any shape or form, we were in constant correspondence regarding fitting dates. From visiting our home and sending quotation was so straightforward. We order a large bay window, wasn’t quite sure if this would work on our existing window frame — we were reassured this wasn’t a problem, the cost was well in our budget, that was a bonus. The fitter’s arrived on time and we so polite and professional, they left everything clean and tidy. Absolutely brilliant.

Highly recommend MLR

Highly recommend MLR, just had all new windows and a new front door fitted by them. Amazing service from start to finish, was kept informed every step of the way. Couldn’t fault the guys who came out to carry out the job — friendly, professional, kept the mess to a minimum and cleaned up everything when they were done. Also found them to be much more reasonably priced compared to other quotes I had and found the windows and door to be of better quality.

Frequently Asked Questions

How long will my new windows last?

The lifespan depends on the material you choose. Modern uPVC windows typically last between 20 and 35 years. Composite and aluminium windows are even more durable, generally lasting 30 to 45 years, with some properly maintained installations performing well for up to 60 years. Lifespan also depends on the level of exposure to the Scottish weather and the quality of the installation.

Will new windows genuinely reduce my energy bills?

High-performance uPVC, aluminium, and composite windows are designed to minimise heat loss. Modern rated windows, including A-rated double or triple-glazed units, can help save money on energy costs through better energy efficiency. Upgrading to modern new glazing can save the average household approximately £140 to £300 per year on heating costs while improving the property’s EPC rating, with triple glazing offering greater thermal performance.

How long does the installation process take?

For a standard residential property, most window replacement projects are completed within one to two days, depending on the number of units being installed and any structural considerations. Our installers aim to complete the job efficiently with minimal disruption for customers.

Are your windows fully guaranteed?

We provide a comprehensive 10-year guarantee on our window installations, giving you total peace of mind regarding the quality of our craftsmanship and the durability of the products we supply. If you want to ask about replacement cost and guarantees, you can request a free no obligation quote.

Are your double glazed windows effective at blocking out street noise?

Upgrading your windows can reduce external noise transmission by 25 to 35 decibels. If you live on a busy street with lots of external noise, our modern double glazing will significantly improve your acoustic comfort indoors. Opt for triple glazing if noise is a major concern for you.

Noise reduction often improves further when older windows and doors are replaced together. If you’re also upgrading doors, modern doors can support insulation and security, with multi-point locking systems as standard.
